Answer:
If there is "p" pounds of peanuts and "m" pounds of '20% peanuts and 80% almonds' mixture, then, we can get the following equations,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
whose solution is 5 lb peanuts and 5 lb mixture.
Step-by-step explanation:
In the mixture which Delaney wants to make there would be
lb
= 6 lb of peanuts
So, there will be (10 - 6) lb
= 4 lb of almonds
If Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then according to the question,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
So, from (2),
m = 5 --------------(3)
So, from (1) and (3) ,
p = (10 - 5) = 5
Negative exponets are like normal ones
ex. 2^-2=-4 another way to do it 2^-2=2^2 with a - so you can do 2^2=4 add the - and it becomes -4.

Divide the distance on the map by 2 to get the number of 8km segments there are, then multiply that by 8km for total distance.
16 cm / 2cm = 8
8 x 8km = 64km total.
Answer: A reflection across the x-axis keeps the x-coordinates the same but flips the signs of the y-coordinates. So, it should be the opposite for a reflection across the y-axis. The y-coordinates remain the same, but the signs of the x-coordinates change.
